Description

Portable water purifying device

Technical field

The utility model relates to portable water filtration and purifier.

Background technology

Portable water purifying device is usually used in taking from right water source and filtering, purify in the travelling way, and it is processed into drinkable water.The portable water purifying device claimed structure simply, operate easily, be convenient for carrying.The portable water purifying device of existing straw type, the user must drink up water in the suction pipe upper end with mouth from the water source of suction pipe lower end, make water through inner several filters.Though the aperture of the filter in the portable water purifying device is more little, the impurity that can filter is just many more, if but the aperture is too little, and artificial mouth is inhaled the difficulty that will become, therefore the portable water purifying device of straw type can not adopt the too little filter in aperture, causes its filter capacity not high.And the aperture of filter is more little, and is just easy more blocked, is not easy to change and clean and be positioned at inner filter.In addition, during with the disinfectant water purification, water preferably can be by the sufficiently long time of disinfection and isolation, but existing portable water purifying device is not accomplished this point.Following background technology can be skimmed.

Contaminated drinking water is the one of the main reasons that the world today causes health problem.Though the whole world has only millions of people can run into such problem in daily life, and in those more underdeveloped countries, this problem is especially general, but guarantees to supply with the safety of water and also be a problem for the safety of soldier, hiker, international travelers and other people supply water in developed country.It is common that some well-known water spreads disease in untreated water, and this class disease is by comprising the protozoan parasite of causing giardiasis and circle sorosphere parasitosis (Cyclosporasis) and the microorganism agent of Cryptosporidium parvum (Crytosporidium parvum), causing such as the virus of hepatitis A and other virus etc. and such as the bacterium of Escherichia coli, the Salmonella typhi that causes typhoid fever, comma bacillus, Shigella (shigella species) etc.Symptom comprises heating and diarrhoea, fash, spasm, jaundice, hepatopathy and other diseases, though and in most of the cases, take care of if obtain very soon, these diseases just can be cured so, if but do not treat, the state of an illness may worsen, and causes nonvolatil serious symptoms and death, and is especially true concerning young, old and previous those the impaired people of immune system.

Except untreated water, the supply water of many processing also may contain pollutant.Though most of cities of developed country and big small towns have large-scale pipeline water system (piped water system), in order to high-quality relatively processing water is transported to the user continuously, but have only this running water fully to be handled and sterilize, and have only water system operation normal and be subjected to safeguarding well that this running water just is fit to safety and drinks.Bottled water is also more and more welcome, though and most of user it has been generally acknowledged that bottled water is safe, but they also may be polluted, and not only are subjected to the pollution of all those microorganism harm as has already been mentioned above, but also are subjected to the chemical hazard of any number and the pollution of physics harm.Possible chemical hazard comprises lead, arsenic and benzene, and physics harm comprises glass fragment and metal fragment.

Have many mancarried devices of filtering and purifying waste water of being used in the prior art, these devices are all attempted to make and are come from untreated water source such as lake and river, safeguard that perhaps the supply water of not good pipeline and the supply water at other water sources become drinkable.For example, known straw type device (straw-type device), wherein the user places his or her mouth at one end of elongate housing, and the other end dangles in supplying with water, the user will inwardly inhale according to the mode identical with the suction pipe of routine, so that the water access to plant, and move through one or more filters.The practical problem that this suction filters and purifier (suction filtering andpurifying device) exists of prior art is, the hole of measuring with micron in the filter element is restricted to how little, and can make the particle of having determined much sizes can be by the aperture of filter.Although the aperture of known filter is more little certainly, will be many more from microorganism and other pollutants of the solution removal by filter, but with regard to the suction tube device of routine, in fact the aperture of filter can not make too for a short time, because if too little, the user only will become extremely difficult by applying artificial suction pump up water by filter.On the other hand, the employed aperture of this artificial suction pipe is too big, just can not filter out many harmful pollutants, makes that this suction pipe of prior art is not very effective.For example,, filter out and have 0.2 micron all bacterium usually, just need 0.2 micron maximum diameter of hole to 10 micron-scales though 4.0 microns maximum diameter of hole can filter out giardia lamblia packing (Giardia cysts).Though the size range of many viruses is usually at 0.0004 micron to 0.1 micron, can not be filtered out by most of filters to such an extent as to this size range is too little, but many viruses will self be attached on the bigger host bacterium, and thereby can be removed by removing bigger host bacterium.Another problem of water filter generally is, the aperture of filter is more little, and it is stopped up and to become invalid speed fast more, makes the filter with smaller aperture due to clean more continually or to replace than the filter with larger aperture.Another FAQs with water filter existence of small-bore is that pollutant that they have been removed from water soon and material stop up.Therefore, must constantly replace this filter with new, clean filter, even because to kill harmful parasite and analog filter is sterilized by filter being immersed in liquid lime chloride or the similar solution, but this pollutant still is present in the filter, also may be no longer harmful although eat this pollutant.This is in a more not rich country especially problem, even wherein portable filtration is distributed to the public, so as long as filter is new, just can obtain to clean and the drinkable water of people with filter, if but replace filter be expensive, infeasible and can not and for it, in case filter is stopped up so, it is useless in fact that this device will become.

Another problem of known portable straw type water filter is, they do not allow water to be isolated, and do not allow water to be handled with specific disinfectant to be reached the complete destroy contaminants of this reagent desired time of contact.For example, must mix with water and contact a few minutes such as the disinfectant of iodine, and known portable water filtration device can not this situation of realization.The filtration of other types and purifier are known, but they all are heavy, and are not easy to carry and operate, because of rather than real portable.

The above-mentioned many different parts that comprise device 10 can be separated from one another, and therefore, can be cleaned as requested or replace with new parts.For example, in mouth shape parts 24, sleeve pipe 32 and the stopper 70 each preferably is fixed to the end of

first Room

12 and 14 in the mode that is threaded, and thereby, can be easy to dismounting, and when needs, be replaced if regularly clean or just damaged according to above-described quilt.In addition, sleeve pipe 32 can be removed from the far-end 16 that holds first Room 12, thereby can make such disinfectant that holds in first Room 12 be easy to be replaced or change.Similarly, stopper 70 lower end 22 of second Room 14 internally is disassembled, so the user can be easy to when needed, replaces the cleaning of substances in inner second Room 14 or changes them.Prefilter 26 also can be disassembled and be cleaned, or replaces with the new filter with identical or different aperture, and the aperture is as required identical or different and will how dirtyly be appeared to have by the water that device 10 purifies and decide.In some cases, when water seems cleaner, the user may wish to use the prefilter with obviously littler aperture to filter out more granule, if and water is muddy or dirty especially, so at least just begun to have wide-aperture prefilter, to allow this water to be easier to by check-valves 80, and can not stop up, although the aperture that the utility model of discussing below can effectively use is under any circumstance all obviously littler than other known straw type water filtering devices.

Purifier 10 can be fit to have the in fact more filter or the medium of small-bore, because it is unlike the straw type water filtering device of the known routine of the utility model people, it by inner second Room 14 respectively telescopically move into and shift out normal pressure and the negative pressure holding first Room 12 and produce respectively and can make water be drawn through the filter of this small-bore, and thereby this device is more effective aspect drinkable to guarantee water at the removal microorgranic contaminant.Other known straw type water filtering devices only can not be used for relying on being placed into suction or the buffer brake that the mouth on the mouth shape parts applies and implementing suction and just make prefilter or the internal ramp of suitable supply water by having enough little aperture by the user.Yet, with regard to the utility model people's purifier 10, when prefilter 26 is contained in or dips when entering in the contaminated supply water, water is easy to be pumped into and holds first Room 12, when inner second Room 14 upwards being shifted out hold first Room 12 with box lunch operation, the suction or the negative pressure that produce in this accommodating chamber are made a response.Then, when making inner second Room 14, operation retracts when holding first Room 12, the normal pressure that is produced forces water to enter inner second Room 14 by one way stop peturn valve 81, then before flowing out mouth shape parts 24, by one or more cleaning of substances such as activated carbon beds.When bringing into use device 10, inner second Room 14 will be in advanced position in holding first Room 12, remove cover 30, and prefilter 26 is placed in the supply water of to be filtered or purification, water can be from source lake, river or other processing or untreated.Preferably, this water does not contain visible pollutant as much as possible, and can be filtered earlier by cotton shirt or cloth or analog, enters in the clean container to remove most of very large or pollutants of being easy to see again.Then, as mentioned above, when prefilter 26 remains in this supply water, with manual mode inner second Room 14 is upwards skidded off the near-end 18 that holds first Room 12, this moves generation suction, water is pulled enters by prefilter 26 and via the passages 34 in the sleeve pipe 32 to hold in first Room 12.Be isolated in after the duration that holds the processed expectation of water in first Room 12, impel inner second Room 14 in holding first Room 12, to return to advanced position subsequently, perhaps as shown in Figure 4, the mouth on mouth shape parts 24 of perhaps choosing.When impelling inner second Room 14 to get back to hold in first Room 12, the water that prevents to hold in first Room 12 flows out via the passage in the sleeve pipe 32 of accommodating chamber far-end 16 34 by one way stop peturn valve 80, and thereby, force water to enter inner second Room 14 by the passage 78 in the stopper 70.At last, enough water has entered inner second Room 14, so that interior chamber filled up substantially, and normal pressure is enough greatly to force this water through any filter and cleaning of substances in inner second Room 14 and flow out mouth shape parts 24.

Shown in Fig. 2 and 3, protective cover 30 also can have apotheca 88 in its lower end, can be stored in the apotheca space 86 such as standby supplies (spare supply) such as the iodine resin (a soupspoon amount) of new supply or other disinfectants.Apotheca 88 is fixed on the protective cover 30 by for example suitable manner such as threaded cap structure or frictional fit.

The defective that the portable water filtration device of prior art exists is, filter will soon be filtered the pollutant that device captures and stop up, unless and removed this pollutant, or provide new filter to replace plugged sereen, inefficacy otherwise this device becomes soon.Thereby the utility model people provides as the improvement that is used for quickly and easily pollutant being flushed out prefilter of the part of this device and has arranged, removes the tamper of prefilter thus basically and makes it clean and recover its practicality.More particularly, device 10 is arranged so that as mentioned above the prefilter 26 that is fixed to sleeve pipe 32 removably by screw thread 36 can remove from sleeve pipe 32, and, be fixed to mouth shape parts 24 via the screw thread on the outer surface of mouth shape parts 64 by identical screw thread 36.In such position, by device 10 and prefilter 26, the water that enters prefilter 26 by mouth shape parts 24 is opposite direction to clean water in the above-mentioned mode that is used to filter this water.The strength of flushing by the reverse water of prefilter 26 makes near the most of pollutants the outer surface that is captured and accumulates in prefilter 26 be rinsed out filter material, remove the tamper of filter thus, make the device 10 that prefilter 26 can be fixed to the sleeve pipe 32 on the far-end 16 that holds first Room 12 once more and use in the manner described above.Had been found that before this filter is eliminated tamper basically clean water only need be according to what describe just now, pumping is by prefilter 26 limited number of times in opposite direction.In fact the layout of describing will infinitely prolong the service life of main filter at present, because prefilter can be according to the mode repeated washing of describing just now and used with device 10 again.Certainly, when by this way prefilter 26 being cleaned or removing tamper, filter should be passed through in the clean water source basically.In addition, prefilter can be immersed in liquid lime chloride or the similar solution as mentioned above, to guarantee to kill any remaining micro-microorganism that may be harmful in the prefilter.If the water that use maybe may also contain pollutant from impure source is next according to the cleaning prefilter of describing just now, in case prefilter is fixed to the end and the mouth shape parts 24 that hold first Room 12 once more and is fixed to inner second Room 14 in the mode that is threaded so, it is desirable to, the clean water of one tittle should pumping pass through filter, and outflow mouth shape parts, with before consuming this water, attempt to kill or wash out any material that may be harmful on the inner surface of the surface that may accumulate in mouth shape parts or filter.

In addition, mouth shape parts 24 comprise removable lid 90, and lid 90 is fixed to screw thread 64 (referring to Fig. 2) on mouth shape parts 24 outer surfaces in the mode that is threaded, and this lid 90 also has the wrist strap 92 (referring to Fig. 5,6) that is connected to it.Steam vent or slotted eye (not shown) that hollow is preferably arranged, one end is arranged on the outer surface of mouth shape parts 24, when placing on the container 30 that device shows best as Fig. 4, and mouth shape parts 24 extend down in the container 30, and when replacing air in this container from device 10 the water of pouring container 30 into, steam vent or slotted eye are as the outlet of the air of escaping out from drinking container 30; And, another steam vent can be set to be positioned at and to pass that mouth shape parts 24 extend and contiguous water outlet through hole 58 places, like this in the mouth of airport conventional plastic water bottle that mouth shape parts 24 closely are pressed into have narrow mouth or kettle, to prevent that water from spilling, thus, the air that is replaced by water in the bottle can flow through this airport.Mouth shape parts 24 also preferably use the process of explanation in more detail below, are dipped into Nano silver solution, and this surface that will make mouth shape parts is electrostatic attraction bacteriums.As illustrated in Figures 5 and 6, rotatable dial 96 preferably is fixed on the external surface peripheral of mouth shape parts 24, the end face 62 of contiguous peripheral lip 60.Dial 96 comprises the arrow 98 that indicates the dial position, and in addition, the end face 62 of peripheral lip 60 comprises sequenced metering or count tag 100.Dial or count tag are set have passed through the number of times of device 10 with the contaminated water that helps the user to follow the trail of certain volume, and also be used to follow the trail of the time that disinfectant should be replaced or prefilter 26 should be rinsed of holding in first Room 12 as supplementary means.Though counting device is structurally simple, but concerning installing 10 suitable use is important, because if device has used disinfectant dilution or lazy weight, perhaps prefilter or other filters are not regularly cleaned, and Zhuan Zhi operation and whole effect thereof may obviously be included so.

In addition, can in water, add many different vitamins or other nutrients for filtering and providing drinkable drinking water source, the utility model people also to have been found that.Thereby device 10 not only provides drinkable water source, but also the source of the micronutrient that all lacks as most of populations in the world.The common mineral matter that most of people lack is zinc, iron and iodine, and many vitamins, as Vitamin C and vitamin D.For operative installations 10 distributes this nutrients, preferably,, earlier micronutrient is placed to have the separable of housing region 112 and hold in the member 110, and the bottom surface 116 of housing region 112 has hole 114, and its top edge has and covers 120 as Fig. 7,8.Filter or sieve 118 and be arranged on the bottom surface 116, the micronutrient of dissolving can pass hole 114.Lid 120 can be installed in the lower end or the upper end of inner second Room 14, and perhaps alternately, lid 120 can be sized into the inwall of being close to second Room 14.Hold the material that member 110 can hold further purification, the water in the device 10 will perhaps hold member 110 and can also comprise the medicine such as vaccine or analog that distributes by device by the material that purifies.

The key improvements part of the utility model people's portable water filtration device 10 is to filter out most of pollutants via prefilter 26 in the starting stage, so that any water for the treatment of further to handle of access to plant 10 is by prefilter 26, and thereby enter hold first Room 12 before, obviously do not contain pollutant.By test, the utility model the people also have been found that, the prefilter 26 of preferably being made by the porous polypropylene material of those skilled in the art's known type and can obtaining from many sources can have 35 microns or littler aperture, is small enough to filter out most of pollutants.In addition, the utility model people has been found that having about 60/1000000ths inches thick and layer or coatings that contain the nano-Ag particles of 10 the silver atoms sizes of having an appointment can be applied to the surface of prefilter 26.In preferred the layout, be coating nano-Ag particles coating, prefilter is immersed in the aqueous isopropanol of this nano-Ag particles that contains 500ppm long number second.When from solution, taking out, the very fast evaporation of alcohol, and silver-colored particle is captured or attached in the prefilter.Because silver-colored particle is with respect to the small size in prefilter aperture, so the within and without of prefilter all scribbles this silver-colored particle.As everyone knows, silver ion can be used to kill or eliminating bacteria; Yet by to the utility model people's prefilter coating Nano silver solution, the utility model people's test has been found that when by prefilter, and about 98.6% the bacterium that contact with particle just was eliminated or has eliminated before access to plant 10 with viral.When the resin of dipping iodine was used as the disinfectant that holds in first Room 12, the Nano Silver coating had also prolonged the service life of the resin of dipping iodine, because iodine is (demand-released) that discharges as required from this particle.In another was preferably arranged, iodine resin and arsenic resin all were arranged on and hold in first Room 12, had been found that these two kinds of disinfectants can not react together, and these two kinds of disinfectants are eliminated any packing in the water in electrochemical mode.At another improvements, the utility model the people have been found that, when this container of injection moulding, Nano silver solution can be immersed in the polycarbonate container 30, so that any bacterium with contacting with the nano-Ag particles that exposes on the inner surface of container of pouring in the water in the container has all been eliminated.Just as described above; nano-Ag particles can also be applied to the surface of the miscellaneous part of device 10; as mouth shape parts 24, container 30 or drinking glass and place the end of inner second Room 14 polypropylene filter, micronutrient dispense container 110 filter 118 or be used for cleaning of substances is contained in second Room 14 or at these indoor other separators that are separated out the granular activated charcoal bed, so that bacterium kill ratio maximum of the present utility model.

The main advantage of the embodiment of describing is tangible at present, be normal pressure and negative pressure owing to the greater amount value of the pump action generation of passing through device, so prefilter 26 can have very little filter size, while still can make the water of q.s move through device and be cleaned, and thereby a large amount of pollutants can be stayed the outside of device 10.In addition, water can be isolated in and hold in first Room 12, and be subjected to the effect of disinfectant, then before flowing out mouth shape parts 24 with drinkable supply water form, the reagent by granular activated charcoal bed or other electrostatic attraction bacteriums enters inner second Room 14 and the filter.Increase cover/container 30; it not only protects prefilter 26; but also as drinking glasses and as the storage area of resin; and can remove prefilter 26 fast and be connected to mouth shape parts 24; so that flushing water is oppositely by prefilter and remove the tamper in its hole, this has further improved and has installed 10 validity.The Nano Silver coating is applied on the prefilter 26 also not only supplying with water also before the access to plant 10, eliminate a large amount of bacteriums, but also prolonged the service life of holding the disinfectant resin that discharges as required in 12, greatly prolonged the probable life of resin and device thus, simultaneously counting device is arranged on the mouth shape parts and should be replaced as working as this resin and granulated carbon reagent, during perhaps as if possibility, the visual detector that device is cleaned fully.Other improvements and the variation of this device have also been imagined.For example, device 10 can be arranged in the plastics reservoir vessel, and when needing, this reservoir vessel can also be as bigger water storing chamber.In addition, device can add the reservoir bag of separable soft type, and these reservoir bags are avoided device to be subjected to the destruction of blunt power and are subjected to because of being exposed to direct sunshine for a long time according to the illumination infringement that causes.
